City scientist solves snail fever puzzle
Kate Mitchell studied snail fever – a neglected tropical disease that affects more than 100 million people in sub-Saharan Africa – as part of her PhD at Edinburgh University’s School of Biological Sciences.
People are infected when worm larvae, released into freshwater ponds and rivers by infected snails, burrow through their skin.

Miss Mitchell, 29, found that the body’s immune response was only triggered once the parasitic worms, which can live in human blood for up to 30 years, start to die.
She said: “This study will help further research to inform the optimum duration and intensity of drug programmes to target the disease, while ensuring an individual’s ability to build up immunity to it is not hampered, as well as help research to find vaccines.”
